【摘要】：本论文的研究问题是朝阳沟油田的精细开发时,其中构造解释不细而造成的认识不清等问题,通过使用井震结合的三维地质模型来控制表现该地区的构造特征,获得了一定新的思路。论文中使用的测井曲线如声波曲线受到扩径等影响,基线不一致,出现了偏移,甚至曲线范围不一致的情况,寻找了测井曲线标准化的方法,分别对自然电位和声波曲线等进行标准化。密度曲线使用相关曲线的拟合方法来重新制作密度曲线。本次项目使用地震来控制构造形态,单井的数据来控制位置,在这样的分析中来完成朝44区块断层解释和断点的组合。综合的使用测井数据中的断点数据,分层深度和提取地震属性,从点到面的对断层分形分析,落实构造的形态,完成朝44油田的断层模型。在断层模型的约束下,把地震解释的层位和测井分层深度统一,制作出朝44区块的构造模型,并在沉积相模型的约束下完成了该区块的精细属性模型。通过本论文,得出了完整的井震结合三维地质建模的流程和方法,这样在后续该区块开发过程可以有很大的价值。
[Abstract]:The research problem in this paper is that in the fine development of Chaoyang Gou oilfield, the structural interpretation is not very good and the understanding is not clear, and so on. The 3D geological model combined with well and earthquake is used to control and express the structural characteristics of this area. Some new ideas have been obtained. The logging curves used in this paper, such as the acoustic curves are affected by the expansion of the diameter, the baseline is inconsistent, the migration occurs, and even the range of the curves is inconsistent. The method of logging curve standardization is found. The natural potential and acoustic wave curves were standardized respectively. The density curve was remade by the fitting method of the correlation curve. The earthquake was used to control the structure shape in this project. Single well data to control the location, in such an analysis to complete Chao44 block fault interpretation and fracture point combination. Comprehensive use of logging data in the fracture point data, stratification depth and extraction of seismic attributes. The fractal analysis of faults from point to surface, the implementation of structural shape, the completion of the fault model of Chao44 oilfield. Under the constraints of fault model, the seismic interpretation of the horizon and logging stratification depth unified. The structural model of Chao44 block is made, and the fine attribute model of Chao44 block is completed under the constraint of sedimentary facies model. Through this paper, the complete process and method of well shock combined with 3D geological modeling are obtained. In this way in the subsequent development process of the block can have great value.
